Combined Heat and Power (Cogeneration) Systems

Combined heat and power process also known as cogeneration, is the simultaneous production of thermal and electric energy from a single fuel source (oil, gas, biomass, biogas, coal, etc.)

Currently the CHP systems are affordable not only for commercial buildings but also for homeowners.

The CHP engines producing electricity that can be internal combustion or Stirling engines. The micro-CHP installations applicable for residential buildings usually run on propane, natural gas, or even solar energy or biomass.

The CHP systems offering combined heat and power have efficiency of approximately 90%.

The Alfagy is a distribution company of heat and power products in Europe and the USA based on CHP technology. The website provides information about the CHP technology and extensive information about different CHP plants and technologies.

The website information is related to design and installation of different modular combined heat and power systems. Complete technical specification list for different cogeneration modules is also available.

Global information about different gas generators, cogeneration systems, and distributed energy solutions are presented on the website. Case history and technical papers for some specific cogeneration modules are also available on website.

American DG Energy Inc. is the leading on-site utility offering clean combined heat and power production facilities. The web site provides extensive information about advantages of different cogeneration installations. Additional information about technologies and methods for cogeneration is provided.
